Method And Apparatus For Reproducing Data And Recording Medium

Abstract

A recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. The recording medium for recording data includes: first reproduction-restriction information of the recording medium; and update information of second reproduction-restriction information of other recording medium. If the content provider (CP) desires to release reproduction-restriction of pre-introduced content data at a region or country due to the reproduction environment or other conditions associated with the data reproduction, the content provider provides reproduction-restriction release information via new recording medium including other contents. The user can buy the new recording medium and receive restriction release information from the content provider (CP) without paying the usage fee of reproduction-restricted contents, thereby freely employing desired contents having been protected from being reproduced.

       5 . The recording medium according to  claim 4 , wherein the time information is defined for each region. 
   
   
       6 . The recording medium according to  claim 1 , wherein the update information includes server information indicating a server which provides updated region information or updated time information of the other recording medium. 
   
   
       7 . The recording medium according to  claim 1 , wherein the update information is defined for each title recorded in the other recording medium. 
   
   
       8 . The recording medium according to  claim 1 , wherein the update information is recorded in a secure area of the recording medium. 
   
   
       9 . A method for reproducing data recorded in a recording medium and/or a storage comprising:
 reading updated reproduction-restriction information associated with other recording medium from the data; and   storing the updated reproduction-restriction information.   
   
   
       10 . The method according to  claim 9 , wherein:
 the updated reproduction-restriction information is stored when the updated reproduction-restriction information is different from pre-stored reproduction-restriction information.   
   
   
       11 . The method according to  claim 9 , wherein the updated reproduction-restriction information includes region information indicating a reproduction-allowed region of the other recording medium. 
   
   
       12 . The method according to  claim 9 , wherein the updated reproduction-restriction information includes time information indicating a reproduction-restriction release time of the other recording medium. 
   
   
       13 . The method according to  claim 9 , wherein the updated reproduction-restriction information includes server information indicating a server which provides either the data or reproduction-restriction release information of the other recording medium. 
   
   
       14 . The method according to  claim 13 , further comprising:
 receiving the release information from the server using the server information.   
   
   
       15 . A method for reproducing data recorded in a recording medium and/or a storage comprising:
 determining whether reproduction-restriction of the data is released by referring to update information of reproduction-restriction information associated with the data; and   determining whether to reproduce the data according to the determined result.   
   
   
       16 . The method according to  claim 15 , wherein the update information is recorded in a recording medium which comes out to a market after the recording medium of  claim 15 . 
   
   
       17 . The method according to  claim 15 , further comprising:
 if region information included in the update information is equal to setup region information of a reproduction apparatus, allowing a reproduction of the data   
   
   
       18 . The method according to  claim 15 , further comprising:
 if time information included in the update information indicates that the reproduction-restriction period of the data is expired, allowing a reproduction of the data.   
   
   
       19 . The method according to  claim 15 , further comprising:
 receiving updated region information or updated time information associated with the data from a server denoted by server information, by referring to the server information included in the update information.   
   
   
       20 . An apparatus for reproducing data recorded in a recording medium and/or a storage comprising:
 a reading unit reading updated reproduction-restriction information associated with other recording medium from the data;   a storage unit storing the updated reproduction-restriction information; and   a control unit controlling the reading unit and the storage unit.   
   
   
       21 . An apparatus for reproducing data recorded in a recording medium and/or a storage comprising:
 a storage unit storing updated reproduction-restriction information; and   a control unit determining whether reproduction-restriction of the data is released using the updated reproduction-restriction information, and determining whether to reproduce the data according to the determined result.   
   
   
       22 . The apparatus according to  claim 21 , wherein the updated reproduction-restriction information is recorded in a recording medium which comes out to a market after the recording medium of  claim 21 . 
   
   
       23 . The apparatus according to  claim 21 , wherein the control unit controls the data to be reproduced when region information included in the updated information is equal to setup region information of the reading unit. 
   
   
       24 . The apparatus according to  claim 21 , wherein the control unit controls the data to be reproduced when time information included in the updated information indicates that the reproduction-restriction period of the data is expired. 
   
   
       25 . The apparatus according to  claim 21 , further comprising:
 a transceiver connected to a server,   Wherein the control unit receives updated region information or updated time information associated with the data from the server denoted by server information included in the updated information.   
   
   
       26 . A method for recording data in a recording medium comprising:
 generating first reproduction-restriction information associated with the recording medium and update information of second reproduction-restriction information associated with other recording medium; and   recording the first reproduction-restriction information and the update information in the recording medium.   
   
   
       27 . An apparatus for recording data in a recording medium comprising:
 a recording unit recording the data in the recording medium; and   a control unit generating not first reproduction-restriction information associated with the recording medium and update information of second reproduction-restriction information associated with other recording medium, and controlling the recording unit to record the first reproduction-restriction information and the update information in the recording medium.
